Yolo2Pascal-Annotation-Conversion

Perform conversion between YOLO annotation format and PASCAL VOC format and vice versa. Code based on LabelImage repo.

Usage:

  • Images must be in .jpg/.png format.
  • YOLO to PASCAL: The script will search for all .txt files in the folder and perform the conversion. Converted PASCAL annotation files have a .xml extension, reside in the same folder and share the same name with their corresponding images.
  • PASCAL to YOLO: The script will search for all .xml files in the folder and perform the conversion. The script requires a file class.txt describing all classes (this file is generated autonomously if using the LabelImage tool above for annotating images). Converted YOLO annotation files have a .txt extension, reside in the same folder and share the same name with their corresponding images.

Demo:

  • YOLO to PASCAL:
    • python3 yolo2pascal/yolo2voc.py demo/yolo2pascal
    • After this, 2 files cat.xml and dog.xml should appear in the demo/yolo2pascal folder. They are label files in PASCAL format. You can use LabelImage to load the directory using PASCAL format to check.
  • PASCAL to YOLO:
    • python3 pascal2yolo/voc2yolo.py demo/pascal2yolo
    • After this, 2 files cat.txt and dog.txt should appear in the demo/pascal2yolo folder. They are label files in YOLO format. You can use LabelImage to load the directory using YOLO format to check.
  • Example of class.txt file. They are just labels listed in an alphabetical order:
    • cat
    • dog

TODO:

  • Remove Qt dependency
  • Add support for different image formats (thanks guysoft)
